''Structural superposition'' refers to the optimal superposition, yielding the closest fit, in three dimensions, between two or more molecular models. It is sometimes called ''structural alignment'', but that term more often denotes a sequence alignment | ''Structural superposition'' refers to the optimal superposition, yielding the closest fit, in three dimensions, between two or more molecular models. It is sometimes called ''structural alignment'', but that term more often denotes a sequence alignment guided by a structural superposition. In the case of proteins, structural superposition is often performed without reference to the sequences of the proteins. When the models superpose closely, it suggests evolutionary and functional relationships that may not be discernable from sequence comparisions<ref>PMID: 10686110</ref>. | ||
The purpose of this article is to help in choosing a server or software package for performing structural superposition. Characteristics of structural superposition servers and software packages are listed, along with results of testing with a few examples. | The purpose of this article is to help in choosing a server or software package for performing structural superposition.
